# KVision

Object oriented Web UI framework for Kotlin/JS.

KVision allows you to build user interface of modern web applications with the [Kotlin](https://kotlinlang.org) language.
It's designed to be object oriented in the "most classical" sense - it gives you a hierarchy of many different components,
which are used to build application UI.

Unlike most of the popular web UI frameworks (AngularJS, React, Vue.js and others),
KVision is not declarative - it is not designed to mix HTML code (or pseudo code) with a typical
programming language like JavaScript. In KVision everything is just written in Kotlin, and your code can be reused not by creating any templates,
but by using well known OOP design patterns - composition and inheritance.

This design is quite similar to many non-web UI programming libraries including Swing (Java), QT (C++) and WinForms (C#).

**KVision is a new project in a development phase. Please create an issue for any bugs or feature requests.**
